WINDING MACHINE.

Application filed May 22, 1922. Serial No. 562,606.

To all whom it may concern.

Be it known that I, ALoNzo E. RHOADES, a citizen of the United States, and resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Winding Machines, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to a machine for winding yarn upon a yarn receiver in the nature of a spooler.

The object of the invention is to provide a machine which will windsimultaneously yarn from a plurality of yarn carriers such as bobbins onto a corresponding plurality of yarn receivers to enable large masses of yarn to be wound onto the receivers by piecing the ends of successive yarn carriers and in which the yarn shall bewound upon the yarn receivers with a filling wind.

' The object of the invention is to provide a simple and efiicient mechanism in a winding machine of this type which will produce the desired filling wind on the yarn receivers.

The nature and objects of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

In the drawings;

Fig. 1 is a front elevation of a portion of a winding machine embodying a preferred form of the invention with only suchparts illustrated as are necessary to a disclosure of the invention;

Fig. 2 is a view in transverse vertical section of the construction shown in Fig. 1;

Fig. 3 is a detail in plan view of a portion of the pick motion mechanism,

This invention is particularly designed for winding large masses of yarn with a filling wind upon receivers in the form of spools having but one head. It is desirable to have such large masses of yarn wound with this filling wind upon spools of this type particularly in connection with the manufacture of cords such as are employed in automobile tires. The yarn from several of the receivers wound in accordance with this invention is twisted together to form a strand and several of these strands in turn are twisted together to form the desired cords. In these operations it is found desirable to have the yarn in as long continuous strands as possible and the operation is much facilitated if these strands of yarn can be drawn off from the end of the spool rather than off from the side as is the case when the it is drawn off from the spool the spool rotates on its axis and the speed of rotation of the spool and the tension of the yarn varies continuously throughout the entire unwinchng operation.

In this invention wherein means are provided for producing a filling wind upon the yarn receivers or spools the yarn is unwound therefrom by drawing it off in line with the axis of the spool, there is no rotation of the spool, and while the tension on the yarn varies somewhat as each conical layer comes off the tension subject to this variation remains the same throughout. the entire unwinding operation.

In this type of winding machine the yarn receivers or spools are preferably arranged in two rows extending along the front and the back of the machine and the yarn carriers which feed the yarn to the spools are arranged in two corresponding rows and the operation of winding goes on simultaneously with respect to all of the yarn receivers or spools.

The frame of the machine comprises suitable supporting uprights 1v connected longitudinally by beams 2 and rods 3. Longitu dinal members of the frame are connected transversely by suitable cross struts l, All of these members may take any suitable and desired form, Each yarn receiver as employed in this invention consists of a single head 5 and a barrel 6 provided with a conical base connecting it to the head. Each of these spools is mounted on a spindle driven by a whorl 7 and these whorls and spindles are located as noted in two rows on top of the beams 2. A windin rotation is imparted to each of the whorls by bands 8 extending about a drum 9 mounted on'the main shaft 10 extending longitudinally of the ma chine. Power is communicatedto the Shaft in any suitable manner as through the fast and loose pulleys 11, 12.

c Theyarn, carriers are shown in the form of bobbins 13. Each bobbin is'mOunteCl in The gu des 18 are mounted on traverse rods 19 extending longitudinally of the maehine injfront of the spools. These traverse rods 19 are supported by lifting mechanism throiighi which is given the necessary travsefl oti i a a v I jThe lifting mechanism in the form illus- 1 trated comprises avpluralit-y ofyoke-shaped members 20, the upper horizontal ends of which are pivoted at intervals along the beams 2, at 21 on uprights 22 carried by the beams. On each pivotalpoint 21. are mountedarms -23 whichare connected by links 24 to thetraverse rods and projections 25 extend fromthe yoke-shaped members 20 be- Death the, 2111118 23. It will thus be seen that i-tthe yoke-shaped ,mernbers 20 be swung clockwise about their pivots 21 the traverse rods 19 with theitraverse guides1$ will be raisedand thatif the y ke-shaped members 20 be swung in the opposite direction. asaby the Weight of the traverse ,ro,ds and connected parts, the traverse rods will be lowered. in i t In-this invention the movement given to thelifting mechanism is such as to provide the desired filling wind. This is caused by giving the traverse rods and the traverse guides. carried thereby afixed length of traverseand by progressively shifting: the c zone of traverse during the winding operation until that operationis completed. Thus durin}; each complete traverse the width of the Zone of yarn wound upon the receiver is the same but as this zonevis progressively diifted throughout the length of the spool the entire spool is finally covered with the desired filling wind. y r lA'simplerand preferred form of mecha nism iforz iefl'ectingt this required movement of the lifting mechanism for the traverse rods-,isillustrated. Thelower ends ot the if) yokesshaped meinbersZQO are connected by, a

Theupper end of the arrnQS of the bell. crank lever is bifurcated transversely and between the bifurcations thereof is journalle'd at 34: a drum 37 A flexible connector in the "Form of a chain 36 is connected at one end as thedrum and at the opposite end to the rod 26. As illustrated a suitable adjustable connection 37 is interposei'l between the end of the flexible connector or chain 36 and the rod. It will thus be s een that it the hell crank lever 27 isrocked on its fulcrum30 the traverse rods 19 with the traverse guides 18 will be raised and 10wered This rockingmovement is eifectekl bv means (it a can] cooperating with the free end oi. the arm 29 of the bell cranklever and i driven preferably from the main shaft of the machine. v

In the construction illustrated abracket 38 is bolted to a suitable'portion oftheitraine such as the uprights 39. This bracket carries h'oriiontally projecting arms 40 in which is journalled a vertical shaft 41 carrying a worin wheel 4+2 and a connected barrel cam 43 which is the cam engaging and operating the freeend of the arm 29 of the hell crank lever. A roller 4ft is joli r nalld in the end of the arm 99 to bear ae'aiiist the tare of the Cam i3.

I The worm wheel 4-2 is rotated by a. worm 45 carried on a shaft 416 iournall'ed at one end on a bracket 47 bolted to the tranie and at t-he other end on bracket 48 proi'ectinq from one of the uprights l. This shaft. is rotated in any uitable manner and for that purposea spro ket chain 49 is illustrated by which the rotation of themain shaft 10 rotates the shafted With the mechanism thusfar illustrated and described the width of the one o't traverse imparted. to the travcrse rods l9 and traverse uideslS would remain constant. In order to secure the progressive shifting of thezoneo'ftraverse a pick motion mechanism is provided. In the form illustrated a bracket 50 is bdlted to the arn QS oi the bell crank leverhan'd this bracket has iournalled thereon preferably in an inclined direction ashaft 51 carrying at its lower end a worm 52 whichm with a worm wheel 53 connected to and rotatine; with the drum 35. Theiipper end of the/ bracket 50 is -formed to present aloif' rated portion 54 in which is urnal d ;a transverseshaft55 carrying a beveledg meshing with a beveled gear 57 onthe upper end of the/ shaft 51. There is also mounted on the shaft aratchet wheel 58. It will thus besseen that if the ratchetwhee] 58 rotateclrotation will also be i and the cha 6w tent swaths between the axis "or the "shed mi ted to point at which the chain is connected to the rod 26 thus shifting upwardly the zone of traverse imparted to the traverse rods 19 and traverse guides 18.

The rotation of the ratchet wheel 58 is imparted b the engagement of the ratchet wheel, as t e bell crank lever 27 is swung, with a relatively fixed pawl 59. This pawl is shown as adjustably connected at its pivotal point 60 in a slot 61 to a bracket 62 secured to one of the beams 2.

VVit-h the construction thus illustrated each time the bell crank lever 27 is swung clockwise by the cam 43 the ratchet 58 engages the-pawl 59 and winds the chain 36 upon the drum thus shifting the zone of traverse and the extent of this shifting movement is determined by the longitudinal adjustment of the pawl 59.

lVhen the winding operation is completed and it is desired to restore the traverse rods 19 to a lowermost position the pawl 59 is elevated to disengage the ratchet 58 and the drum 35 is unwound to lengthen out the chain 36. To enable this to be done readily a hooked rod 63 engaging beneath the pawl 59 and mounted in the flange of the beam 2 is pulled upwardly and locked or held in elevated position. The ratchet wheel is then rotated to unwind the chain. To enable this rotation of the ratchet to be performed readily a sprocket wheel 64 is mounted on the shaft 55 and a sprocket chain 65 runs thereover and about a sprocket wheel 66 journaled in the arm 29 of the bell crank lever. A key may now be placed in the end of the shaft 67 of the sprocket wheel 66 and rotation thus imparted to unwind the drum 35 and chain 36.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is: i

1. A winding machine comprising a frame, a series of yarn receivers and means for rotating them, a series of yarn carriers, a traverse rod provided with guides through which the yarn passes from the respective yarn carriers to the corresponding yarn receivers, lifting means for the traverse rod,a bell crank lever fulcrumed on the frame, a drum journa-lled on one end of the bell crank lever, a flexible connector connected to the drum and to the traverse rod lifting mechanism. a cam acting on the other end of the bell crank lever, means for rotating the cam to rock the bell crank lever and thereby eifect a filling traverse of fixed length, and a pick motion mechanism mounted on the bell crank lever, actuated upon the rocking of the bell crank lever to give a partial winding rotation to the drum and thereby effect a progressive shift of the zone of traverse during the winding operation, whereby the yarn is wound onto the receivers with a filling wind.

2. A winding machine comprising the construction defined in claim 1 in which the pick motion mechanism comprises a worm wheel on the drum, a shaft having a worm engaging the worm wheel, a ratchet wheel, and gearing interposed between the ratchet wheel and shaft and in which a pawl is mounted on the machine frame and co-op- 'erates with the ratchet to effect its partial rotation upon the rocking of the bell crank lever.

In testimony whereof, I have signed my name to this specification.
